Fast delivery and would highly recommend

"Ordered double glazed window for our shop. Dealt with Nathan on the Trade Counter, who was excellent and went above and beyond the usual customer service. Window was very well made and arrived with no problems. Fast delivery and would highly recommend."

The windows look fantastic

"Recently used Dekko Windows to supply the windows and aluminium bi-fold doors for our renovation project. We paid a short visit to their showroom where Rob and Neil were really helpful, showing us around and providing options for us. We were really happy with the whole process and the windows look fantastic. Would definitely recommend this company."
